We should have a 0.22.0rc0 out today with py312 wheel!! If that looks good, we will release 0.22.0 on Friday or Monday morning.

I think we should backport this. The compatibility patch isn't big and this way, we don't have to scramble for a new feature release just for Python 3.12 support.

I will update branch protection after merge. The checks here will show required 2 jobs not running because I renamed them.
